In Washington State, the saltwater Puget Sound is cold and deep. The Army has expensive boats with hyperbaric chambers for deep sea divers.
From the bottom of the Puget Sound, Army divers are removing large fishing nets that entangle fish and wildlife.
"In the U.S., you drive six hours to get to 100-foot depth- with no training being done."
Washington State has a commitment to clean up the oceans. Bravo!
The purpose of doing this is to "clean up the ocean" I promise.
